Y 1o all 'LU/wm it may concern:

Be it known that I, FREDERICK SAMUEL- soN, a subject of the King ot Sweden, residing at Rugby, England, have invented certain new and use't'ul Improvements in Steam-Condensers, ot which the following is a specification.

The invention relates to steam condensers and its object is to provide apparatus of improved construction and increased eiiiciency whereby a better vacuum is secured. This improved apparatus has the general form of a combined surface and jet condenser which can utilize wat-er ot condensation for the spray or jet and adds to the surface condenser the good features of the jet condenser without introducing any of its disadvantages. The jet condenser cools the steam, water vapor and more especially the uneondensed gases more eifcctively than the tubes ot the surface condenser, while by utilizing water ot condensation in the jet condenser the water discharged trom the apparatus is in better condition for use in the boilers ot the plant than it would ordinarily be if water from some outside source were supplied to the jet condenser. It, as seldom happens, a supply ot pure water 'trom an outside source is available, the apparatus can use water from said source in the jet condenser if desired.

1n the accompanying drawing which illustrates one of the embodiments ot the invention, Figure 1 is a longitudinal section ot the condenser; and Fig. 2 is a transverse section on the line 2-2 of Fig. 1, also showing the air pump connections and a pump arranged to take water of condensation trom the apparatus and supply it to the jet condenser.

rlhe apparatus is provided with a casing 3 having heads l. Between' the heads and the ends of the casing are secured the plates or sheets 5 in which the ends ot the tubes 6 are fastened. Exhaust steam enters by the opening 7 at the top ot the casing and water of condensation passes out through the opening 8 at the bottom ot said casing. The interior of the heads t is divided into chambers by partitions 9 which extend :trom the outer portion et said heads into .engagement with the tube sheets The cooling water ent-ers the chamber 10 from a nozzle 11 supplied from any suitable source and flows through the lower set or bank ot tubes to the chamber 12, thence through the set ot tubes 13 to the chamber 14; and through another set of tubes to the chamber 15 from which the cooling water passes by way of the uppermost bank of tubes to the chamber 1G and out through the nozzle 17. The number or' banks of tubes will be determined by the conditions t0 be met by the appar-f tus. The direction of flow is indicated by the dotted arrows.

Th@ jet condenser is arranged between two adjacent banks of tubes. In the form of the invention illustrated, a space or region 19 is provided above the tower bank et tubes 18 tor said condenser. At the lower part ot' this region a plate or partition 20 is supported in any suitable manner just above said bank of tubes. An opening 21 between the end o1' the plate and t-he leit tube sheet 5 permits a fiow from the upper to the lower portions ot the condenser'. Mounted on the plate 2O are a number ot' longitudinally arranged spray pipes 22. The pump 23 draws some of the water of condensation from the lower part ot the coudenser or water from some other suitable source as above described, and by forcing it into the pipes 24 and 22, sprays it into the region 19 to condense and cool the contents of the condenser. The spray and the condensed steam tall on the plate and iow irom the left end of it through the opening 21 and toward the right over the cooling tubes to the outlet S adjacent the opposite end ot' the condenser. The condenser also has an opening or outlet 25 connecting with the region 19. A wet air pump of any approved construction is connected to the pipe 26 leading from the outlet 25 to remove vapor and uncondensed gases from the condenser and also to draw the surplus water of condensation through the pipe 27. A shield or d etlector 28 arranged adjacent the opening 25 is provided with an opening 29 opposite said opening 25.

Steam entering the inlet 7 flows down over the upper banks of tubes and is condensed to a large extent by the cooling water flowing upward through the tubes. The water resulting from the condensation oit' the steam flows toward the bottom of the condenser, falls on the plate 20 and is further cooled by contact with the bank of tubes 18 on its way from said plate to the outlet 8. The steam remaining uncondensed enters the region 19 where it meets the fine spray from the pipes 22. This spray 1ningles with and eondenses the steam and etliectively cools the uncondensed gases. As will be noted, the cooling water liows through the condenser in a direction opposite to the flow of the steam so that the condensed water in the lower part of the apparatus is acted on by the circulating water in its coldest condition. rIhe jet condenser thus cooperates most effectively with the surface condenser to produce a high degree of vacuum and water of condensation is available in the best condition for feeding the boilers, it desired.

In accordance with the provisions of the patent statutes, I have described the principle of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is' only illustrative, and that the invention can be carried Vout by other means.

What I claim as new and desire to secure by Letters Patent of the United States, is,-
